An unprecedented hexagonal double perovskite organic-inorganic hybrid ferroelastic material: (piperidinium)(2)[KBiCl6]


An unprecedented A(2)M(I)M(III)X(6)-type double perovskite adopting a fully hexagonal BaNiO3-type structure, (piperidinium)(2)[KBiCl6], undergoes a 2/mF1 ferroelastic phase transition at 285 K with a spontaneous strain of 0.0615, arising from the order-disorder transition of organic cations together with the synchronous displacement of inorganic chains.
